After oil sample syringe extracts oil sample, the journal stirrup of syringe is hung in installation cavity 311, the stack shell of syringe is passed through
The downward hanging of U-shaped opening 312, proximity switch 313 detects syringe cylinder after one's death, and controller 700 controls clamping device 320 by cylinder
Body is clamped, that is, clamp motor 322 and drive clamping leading screw 323 to rotate forward, and clamping leading screw 323 drives clamping slider 324 inside
Lateral movement, connecting rod 326 drives gripper jaw 325 to be drawn in centre, the pressure sensor real-time detection clamping of the inner side of gripper jaw 325
Pressure between pawl 325 and injection sleeve, after clamp pressure reaches certain value, the control clamping motor 322 of controller 700 stops
Only work, so far, syringe completes to place and fixed.
Step 4：The retaining of syringe injection ram
After syringe is fixed, i.e., after clamping motor 322 is stopped, the control of controller 700 lower piezoelectric machine 330 is positive to be turned
It is dynamic, push turbine gear 331 and drive the screw gear 401 pushed on leading screw 400 to rotate forward, with pushing leading screw 400 just
To rotation, push sliding block 402 and slowly and steadily move downward, when the trigger unit of microswitch 404 on depression bar 403 is injected device
Injection ram triggering after, controller 700 control lower piezoelectric machine 330 be stopped.
Step 5：The withdrawal of dust plug 603
After lower piezoelectric machine 330 is stopped, controller 700 controls dust-proof magnet coil 600 to be passed through 3~5 seconds forward currents
Turn-off current afterwards, when forward current is connected, dust-proof magnet coil 600 produces positive magnetic field force, magnetic field force and lower magnet ring 605
Repel, attract with upper magnet ring 604, make dust-proof magnet coil 600 drive interior iron core 601 to move up, it is final in iron core 601 with
The phase magnetic attraction attachment of upper magnet ring 604, simultaneously because guiding of the guide groove 210 to guide block, interior iron core 601 is in the process for moving up
In, it is rotated by 90 ° in horizontal plane direction, support arm 602 is rotated 90 degree, dust plug 603 is departed from injection port and is avoided syringe
The advance route of syringe needle.
Step 6：The insertion of syringe

It is dynamic, with the positive transmission of longitudinal Vortex wheel gear 501 and longitudinal gear 502 on longitudinal rack 121, movable block 300 it is steady to
Lower motion, after the trigger unit of the triggering pressure switches 503 of movable block 300, the control of controller 700 longitudinal motor 500 is stopped,
Now, in the plug chromatographic injection port of insertion of syringe.
Step 7：Oil sample sample introduction
After longitudinal motor 500 is stopped, the control of controller 700 lower piezoelectric machine 330 is rotated forward again, pushes sliding block
402 move downward and then press the injection ram of syringe and move downward, by the sample introduction of the oil sample injecting chromatograph in syringe
In mouthful, after pushing the trigger unit of the triggering lower position switch 412 of sliding block 402, the control lower piezoelectric machine 330 of controller 700 stops work
Make.
Step 8：The extraction of syringe
After pushing the triggering lower position switch 412 of sliding block 402, the control of controller 700 longitudinal motor 500 is rotated backward, with
The reverse drive of longitudinal Vortex wheel gear 501 and longitudinal gear 502 on longitudinal rack 121, the steady motion upwards of movable block 300,
The syringe needle of syringe is extracted from chromatographic injection port, after the trigger unit of end plate switch 414 is triggered by top board 110,
The control of controller 700 longitudinal motor 500 is stopped, and now, the plug of syringe is extracted from chromatographic injection port.
Step 9：The release of syringe
After longitudinal motor 500 is stopped, the control of controller 700 lower piezoelectric machine 330 is rotated backward, and pushes turbine gear
331 drive the screw gear 401 pushed on leading screw 400 to rotate backward, and with rotating backward for leading screw 400 is pushed, push sliding block
402 smoothly motions upwards, after the trigger unit of the triggering upper limit position switch 411 of sliding block 402 is pushed, under controller 700 is controlled
Medium-voltage Motor 330 is stopped, while lower piezoelectric machine 330 is rotated backward, the folder in the control clamping device 320 of controller 700
Hold motor 322 to rotate backward, gripper jaw 325 unclamps the injection sleeve of clamping, when gripper jaw 325 is expanded to standby initial position
Afterwards, the control of controller 700 clamping motor 322 is stopped, and operating personnel at any time can remove syringe.
Step 10：The sealing of dust plug 603
After end plate 414 trigger units of switch are triggered by top board 110, controller 700 controls dust-proof magnet coil 600 to be passed through 3
Turn-off current after~5 seconds reverse currents, in turn-on reversal electric current, dust-proof magnet coil 600 produces opposing magnetic field power, magnetic field force
Attract with lower magnet ring 605, repel with upper magnet ring 604, make dust-proof magnet coil 600 drive interior iron core 601 to move down, most
Iron core 601 and the phase magnetic attraction attachment of lower magnet ring 605, the guiding due to guide groove 210 to guide block in eventually, make support arm 602 turn round 90
Degree, dust plug 603 finally with chromatographic injection port gluing, sealing, so far sampling device completion work waits sample introduction next time.
